21_24b/2011Solar Cells: Structural and Electronic Properties of Semiconductor-Sensitized Solar-Cell Interfaces (Adv. Funct. Mater. 24/2011)

On page 4663, Christopher E. Patrick and Feliciano Giustino investigate the interface between TiO2 and Sb2S3 found in semiconductor-sensitized solar cells by means of first principle calculations. An atomistic model of the TiO2 and Sb2S3 interface is proposed and the interfacial energy-level alignment and ideal open-circuit voltage are determined. The analysis of other isostructural sensitizers indicates that anti-monselite (Sb2Se3) holds potential for delivering higher energy conversion efficiencies than the TiO2/Sb2S3 system.
